Emerging interactive multimedia applications, such as real-time visualizations, animations, on-line games, virtual reality, and video conferencing have low latency interactions and continuous high resource (e.g., CPU processing and network bandwidth) demands. The combination of latency sensitive interactions and high resource demands is challenging for best-effort platforms, such as the Internet, general-purpose operating systems and Web browsers because these platforms have no timing or resource guarantees and tend to favor high utilization. When demands exceed available...
